PROBLEM TO BE SOLVED: To solve the problems of conventional rice transplanters comprising the large size and heavy weight owing to a transplantation frame used also as a transmission case and unsuited as a popular type having small size and light weight and producible at a low cost. SOLUTION: The supporting and transmitting apparatus 2 for a planting rod 1 is provided with a supporting frame 4 fixed to a supporting member 3 of the driving side at the base end of the frame. The frame 4 is extended to a planting position and a planting transmission case 5 is connected to the tip end of the frame. The base end of a planting transmission shaft 6 for transmitting power to the planting transmission case 5 is connected to the drive-side transmission case 7, the shaft is extended along the supporting frame 4 and the tip end is supported with a bearing to enable the transmission of power to the planting transmission case 5. The transmission case 5 has the planting rod 1 supported at the outer side part with a bearing in a manner to enable the planting action of the seedling.
